Emedastine difumarate inhibits histamine H2 receptor (Ki=49067 nM) and histamine H3 receptor (Ki=12430 nM)[1].
High concentrations of Emedastine difumarate (1 and 10 ng/ml) significantly inhibits type 1 collagen production in normal human dermal fibroblasts[2].
Emedastine difumarate (1, 10, 100, 1000 nM) at concentrations of ≥ 10 nM inhibits CC chemokine-elicited eosinophil migration[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Pretreatment with Emedastine difumarate (0.03, 0.1, 0.3 mg/kg; orally) significantly inhibits the scratching induced by substance P and leukotriene B[3].
Emedastine difumarate (0.3 mg/kg, p.o.) produces significant inhibition of passive peritoneal anaphylaxis in guinea-pigs[2].
Emedastine difumarate inhibits histamine-induced contractions of isolated ileum (IC50=6.1 nM)[2].
